HENRY MOBBS, OF PAERAMATTA, NEAR SYDNEY, NEW SOUTH WALES,

AUSTRALIA.

CASEMENT .AND TRLNSOM STAY AND SASH AND DOOR HOLDER.

Application filed August 7, 1922.

Be it known that l, Geenen HENRY Menem subject ot the King oi' Great Britain and ireland, residingl at 109 Argyle Street, Parramatta, near Sydney, Yew South Wales, Australia, have invented certain new and useful Improvements in Casement and Transoin Stays and'ilash and Boor lolders, ot which 'the following isaspeciiication This invention relates to stays or holders 'for hinged doors and easement sashes, Vfor stayingv or holding; the same 'trictionally in any position in which they may have been adjusted so thatthey will remain in such position notwithstanding' vibration and wind pressure though morable by the application ot a degree of manual torce proiviortioned to overcon'ie the trict-ional adjustment ot the device.

The litting in which the invention consists is usable in connection with slidable sashes and reversibly hung sashes as well as in conneet-ion with hing-ed sashes, and transoms; but it is appropriately fixed in each case having regard to the service required.

rlhe iitting comprises a friction rail with terminal mounting lugs, adapted for mounting' .it on a sash or door or on its frame, a slider sleeve with cork insert forming a collar shoe to run on said `rail trictionally, an adjusting screw attachment for Varying the compression of the cork shoe, and a link or stay bar pivot-ally fixed to a butt plate or to an offset butt bracket, which butt is adapted to vbe fixed to a sash or door or to its trame according to the particular arrangement oi the device adopted in each case.

lin the accompanying drawings Fig. l is a perspective View shewinp; the fitting' used as a easement sash stay with the stay bar pivotaslly centered on a stud plate liked to the frame sill;

Fig. 2 is a fragmentary horizontal section correspending with Fig, l, with the sash shewn in closed position;

F ig. 3 is a sectional plan indicating the movement and relative position of the parts when the sash (Fig. l) is in partly open position;

Fig. lis a top plan view showing the titt-inp; of the device externally to a easement sash using` a butt bracket for the pivotal support of the link, the sash being shown closed in this figure;

Serial No. 580,352.

, Fig. is an elevational view corresponding` with Fig. Zl;

F (i is a plan view corresiiionding with F at but showing the sash in open position; and

Fig. 7 is a 'traonientary sectional elevational view showing' the attachment for adjustine,- the pressure oi" the cork friction shoe on the rail.

lt is to be understood that the device may be fitted to a door or window` either on the top rail, mid-rail or bottom rail position according to the necessities of each case; furthermore that it may be used in connection with rip-swinging or down-swinging transoms to hold the sash in any partly open position to which it may be brought by manual adjustment. The iittingr for transonis will be understood it the drawings bei-cad sideways instead ot erect :is applying to such sashes. F or carrying vertically sliding sashes, as for instance in rail *ay carriages, so as to avoid the necessity tor :fitting counterbalance weights, the rail may be. fixed on the head of the frame and the. pivotal mounting' it'or the link end on thetop rail of the sash. In this case the slider which works on the rail may be provided rith a hand grip to tacilitate the moving' ot it alongthe rail to allow of the sash being raised or lowered readily. It the length of be appropriately proportioned so that when the sash is fully closed down the link sets erect or nearly so, the link will then serve a lock to prevent the torcii'lg up of the sash from a position outside Vthe apartment in which the sash Iitted. lt will be iniderstood that Ytor vcrtical sash mounting according` to this method two ol the iittings may be used to support the sash 'from two points at either side of it instead oit 'from one central point only on its top rail, thereby to obtain better security and better balance.

Referring' to Figs. l to 3:

A is t-he 'friction rail, 1B lun-s on the end of it adapted for mounting` it on a door, sash.r or frame. C the slider, D cork inserts in the slider C, E link. K pivot connection of link to slider C, F pivot connection of link E to butt plate G. The plate Gr is adapted to be xed by screws H.

rlhe slider C may be provided with a screw adjustment (see Fig. 7) for varying the pressure on the cork insert D and thus Avarying` 'the frictional resistance to movealong' the rail A. D is a cork sleeve or shoel contained in a cavity in the sleeve C, with a metal back plate E behind it, and F is a tensionin` screw by which the bearino` resn s P i sure on the cork shoe D may be adjusted. 't is preferred that a cork tubular sleeve should be used rather than a shoe in order to obtain a cork-to-inetal `grin on the top side as wel] as on the underside of the bar. The stem piece G of the sleeve C is rotatably mounted in one end ot the stay link ll; the screw F is tapped up vthrough this stein piece. The other end of the stay link l-l is pivotally mounted at l( in the end of a bracket L, the, butt M ot' which screwed to the 'frame post N on which the door or sash P is lining l by hinges C. The bracket L is set back angularly to allow the sash or door to be swung' open on its hinges past the right-angle position.

In the closed 'position 4) the sleeve C locates near one end of the rail A. As the sash or door l) is opened7 the sleeve C slides along said rail A towards its other end as seen in F rlhe retardation effect on the swingingv movement of the sash or door is controllable according to the degree ot tension applied to the cork shoe D by the adjustingv screw F.

What I claim as my invention and desire to secure by Letters Patent is A. sash or door holder including; a rail provided with means for fixing; the same to a sash or door, an annular casing' sin-roundinp; said rail and slidable along' the sani-e, said casing being provided at its opposite ends with inwardly extending flanges, a sleeve of 'friction material arranged in said casing` and lirietionally engaging said rail. said flanges preventing` axial movement ot" the sleeve relatively to the casing, a plate arranged in said casing and bearing` against said sleeve, a screw engaging; said easingfor varying' the tension ol' said plate, and a link pivotally connected at one end to said easing' and provided atits opposite end with means to facilitate its attachment to a door or window frame.
